The listing itself is not the legal bottleneck. An executor named in the will can sign a listing agreement and market the property once appointed, but the transfer of title through Information Services Corporation cannot happen until the grant of probate or letters of administration is in hand, which typically moves in a matter of weeks once the paperwork is complete in Saskatchewan depending on the estate's complexity.
Build the condition period around the paperwork rather than the other way around. A buyer's lawyer will make possession conditional on proof of the executor's authority, so disclose the estate status upfront in the listing rather than letting it surface as a surprise during the deal, which is what actually causes delays and price chips.
Inherited houses in Willowgrove and elsewhere in Saskatoon often carry decades of work with no permit on file, which an online estimate cannot account for. Joel Dyck's hand-reviewed valuation walks the property and prices it while the estate paperwork is still moving, so the listing is ready the moment the grant comes through.
